摘要

摘要: 以钛白废酸无焙烧直接加压酸浸提钒新技术中得到的浸出液为研究对象。配制硫酸体系中的V(IV)溶液，进行萃取单因素试验以研究P204对V(IV)的萃取性能。通过考察水相初始pH值、萃取剂P204用量、萃取相比(O/A)、振荡时间等因素对萃取的影响，得到不同浓度V(IV)溶液的适宜萃取条件，并初步探究了萃取剂P204对V(IV)的萃取饱和容量和萃取机理。结果表明: 萃取物V(IV)溶液的浓度影响水相初始pH值和萃取剂P204用量的选择，但对振荡时间和萃取相比（O/A）无影响；P204对硫酸体系中V(IV)的萃取性能优良，萃取速度快，饱和容量大；对于1、10、30 g/L的V(IV)溶液，在适宜萃取条件下，单级萃取率分别为90.36%、90.27%、61.37%。

Abstract: The leaching solution was taken as the research object which was obtained from the new process for vanadium production by acid leaching with titanium white waste acid under the pressure without roasting. V(IV) solution in sulfuric acid system was prepared to study on the extraction performance of V(IV) by P204 using single factor tests. The effects of initial pH value of aqueous phase, amount of extractant P204, extraction ratio (O/A)and the shaking time on the extraction were investigated to obtain the optimum extraction conditions of different concentrations of V(IV) solution. The saturation capacity of P204 and extraction mechanism of V(IV) were preliminarily studied. The results show that the concentration of V(IV) solution affects the initial pH value of aqueous phase and the amount of extractant P204, but has no effect on the shaking time and extraction ratio (O/A). P204 has an excellent extraction performance, fast extraction speed and large saturation capacity for V(IV) in sulfuric acid system. For the V(IV) solutions of 1, 10 g/L and 30 g/L, the single-stage extraction rates are 90.36%, 90.27% and 61.37%, respectively, under the suitable extraction conditions.
